Abstract

A burner, in particular, for a motor vehicle supplementary or parking heater, for the burning of liquid fuel, in the presence of combustion air, has a combustion chamber (10), with a jet for the atomization of liquid fuel, arranged before said chamber. The jet has a Venturi tube (11) at the largest diameter end of the diffuser section thereof, opening into the combustion chamber (10), and the liquid fuel is introduced into the Venturi region which is at a low pressure when compared with the upstream end of the diffuser section (12), and through the inlet section (13) of which the air is pumped.
